The folded fabrics that can fit inside a shipping box with the dimensions of 1 foot by 1 foot by 2 feet will be 18.

It should be noted that 12 inches = 1 feet

Therefore, 432 cubic inches will be converted to feet and this will be:

= 432/12

= 36

Therefore the number of folded fabric will be:

= 36 / (1 × 1 × 2)

= 36/2

= 18

After reduction of original size of a document by [tex]30%[/tex]%, the reduction scale is 70% of original size i.e., [tex]70:100=7:10[/tex]

As per the question statement, A photocopier reduces the original size of a document by 30%. We are supposed to find out what is the reduction scale.

Let say the document original size to be [tex]100%[/tex]% and if 30% is reduced by the photocopier, the remaining 70% will be the original size.

Hence reduction scale = [tex]70:100 = 7:10[/tex]

Therefore the reduction scale is 70% of the original size.

Answer:

83.5

Step-by-step explanation:

Median means middle. So in order to get that you need to write the numbers in order and then get the middle number. If the amount of numbers are even then take the 2 middle ones and add the together then divide by two.

89, 52, 78, 92, 98, 64 --> 52, 64, 78, 89, 92, 98

Since you have 2 middle numbers, you must take the middle 2 (78 and 89) and add them.

78 + 89 = 167

Now divide 167 by 2

167 / 2 = 83.5

Answer = 83.5

Step-by-step explanation:

+(-11) is -11. You're "adding" -11 when in reality you're taking away 11 unless:

the equation looks like: -6+(-11)

the answer would be -17 because you're adding a negative to a negative. Taking away from a negative number is simply moving further down the negative number line, which makes the negative numbers "increase" in value

But if an equation looks like: 6+(-11)

the answer would be -5 since you are taking away 11 from a positive number.

Answer:

£168

Step-by-step explanation:

Let the total prize be 8x, then the two prizes will be 5x and 3x.

Then, difference between the prizes = 2x

=> 5x - 3x = £42

=> 2x = £42

=> x = £42/2

=> x = £21

As mentioned above, the total prize is 8x.

So, total prize = 8 × x = 8 × £21 = £168

Answer:

the bottom left graph is a function

Step-by-step explanation:

for questions like this pertaining a graph, you can use the vertical line test. essentially for a function, an x value cannot have multiple y values. so, the function cannot have any two or more points that lie on the same vertical line.

the top left graph is literally a vertical line, so that doesn't work

the top right is a circle. draw a vertical line and you see it always intersects two points

the bottom right graph draw a vertical line. two points again, right?

only the bottom left works with the vertical line test.

The equivalent expression of 14x2 +18x + 5 is 18x + 14x2 + 5, the correct option is D.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

We are given that;

The function  14x2 +18x + 5

Now,

18x + 14x^2 + 5

This expression is equivalent to 14x^2 + 18x + 5, because it has the same terms but in a different order. You can use the commutative property of addition to rearrange the terms in any order without changing the value of the expression. For example:

14x^2 + 18x + 5 = (14x^2 + 5) + (18x)

14x^2 + 18x + 5 = (18x) + (14x^2 + 5)

14x^2 + 18x + 5 = (18x) + (5) + (14x^2)

14x^2 + 18x + 5 = (5) + (18x) + (14x^2)

All of these expressions are equivalent to each other and to the original expression.

Therefore, the equation will be 18x + 14x^2 + 5.

The value of GH is 93.

Given,

Point G is the midpoint of segment FH.

GH= 16x-19 and FG=12x+9.

We need to find GH.

If there is a midpoint between two points the midpoint divided the line between two points into two equal lengths.

Example:

A ________B__________C

AB = BC

We have,

F_______G_______H

G is the midpoint.

GH= 16x-19

FG=12x+9.

FG = GH

16x-19 = 12x+9

16x - 12x = 9 + 19

4x = 28

x = 7

Now,

GH = 16x - 19

      = 16 x 7 - 19

      = 112 - 19

     = 93

Thus the value of GH is 93.

The car travels 62.5 meters in 5 seconds

The car is driving at 45 kilometres per hour

The first step is to convert kilometres to meters

1 km= 1000 meters

= 45×1000

= 45,000

The next step is to convert hours to seconds

1 hour= 3600 seconds

= 45000/3600

= 12.5

The distance travelled in 5 seconds can be calculated as follows

= 12.5 × 5

= 62.5

After calculating equation we have come to find that the value of y is equal to 0.525 is true

An equation is formed by joining two expressions with the equal sign "=". The two expressions on either side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.

Typically, the right-hand side of an equation is assumed to be zero. This does not reduce generality because we can balance it by subtracting the expression on the right-hand side from the expressions on both sides.

We have given 12y - 1 / 2 = 8y + 8 / 5

lets solve it

⇒ 12y - 1 / 2 = 8y + 8 / 5

⇒ 12y -8y = 8 / 5 + 1 / 2

⇒ 4y = 21/10

⇒ y = 21/40

Velocities

t = 1 :      11 m/s

t = 2 :      27m/s

t = 3:       56.33  m/s

t = a:       6a + 1 + 4/a  m/s

Step-by-step explanation:

s(t) = 6t³ + 1t + 4 where s = displacement in meters and t is time in seconds

s(t)  = v(t). t where v is the velocity in m/s and t is time in seconds
So v = s/t

At time t = 1
s(1) = 6 x 1³ + 1 x 1 + 4  = 6 + 1 + 4 = 11 meters
v(1) = 11/1 = 11 m/s

At time t = 2
s(2) = 6 x 2³ + 1 x 2 + 4 = 6 x 8 + 2 + 4 = 48+ 2 + 4 = 54 m
v(2) = 54 /2 = 27m/s

At time t = 3
s(3) = 6 x 3³ + 1 x 3 + 5 = 6 x 27 + 3 + 4 = 169 m
v(3) = 169/3 = 56.33  m/s

At time t = a
s(a) = 6a³ + 1a + 4 = 6a³ + a + 4
v(a) = s(a)/a = (6a³ + a + 4)/a = 6a + 1 + 4/a m/s
